I've been pretty intensely involved with OpenDaylight since the beginning. I'm a researcher at IBM working on SDN and before OpenDaylight, I did a lot of work with, and contributed to, the Floodlight OpenFlow controller. As a result, I heavily contributed to IBM's first OpenFlow controller, which was based on Floodlight, and when IBM was spinning up OpenDaylight, I became IBM's unofficial OpenDaylight technical expert.
